Based on limited published evidence, OR52N1 is an olfactory receptor family member with odorant receptor activity localized to the plasma membrane. The gene's function is characterized primarily through structural annotations from UniProt and Gene Ontology databases. OR52N1 was identified as upregulated in circulating monocytes from HIV-positive individuals predisposed to form atherogenic foam cells 1, though this represents an indirect observation in a disease context rather than direct functional characterization. The biological relevance of OR52N1 expression in monocyte atherogenicity remains unclear.
